Information is the new currency of the global economy. We increasingly rely on the electronic creation, storage, and transmission of personal, financial, and other confidential information, and demand the highest security for all these transactions. We require complete access to time-sensitive data, regardless of physical location. We expect devices -- personal digital assistants, mobile phones, office PCs, home entertainment systems, and a variety of network enabled embedded devices and sensors -- to access that information transparently and work together as one seamless, integrated system.

This trend of ubiquitous computing is the next great computing paradigm shift and will have no less of an impact on industry, government, and daily life than the personal computing revolution. It will create new digital working and life styles which in turn will have profound impact on many vertical industries.

The objective of the Cryptography & Security Department (CAS) is to seek cutting edge security and trust-building solutions in realizing the vision of ubiquitous computing.
